Started Aliens Dark Descent the other day. It's nailed the tense atmosphere of the franchise and it's reproduced the feel and look of the Alien settings well. Very remiscent of the second film. I'm at the end of the second main mission area, though, and as much as I like the setting and tension, there's something that just feels a bit off about the mechanics to me. The tension devolves into frustration trying to get the squad to do what I want precisely enough, manage sight-lines, get my sniper to actually make a shot, all that kind of stuff. Not quite sure I'm going to stick with it despite it's good points.
